This invention relates to an improved lamp socket holding deviceespecially designed with an object of producing an eflective and yetsimple means by which automobile lamp 7 bulbs will be held positively.against displace- I ment from the focal center of the lamp re 'flector.I g V V A further object is to produce a simple and effectivesocketholding devicewhich will be easy to manufacture, inexpensive, andrequire the simplest of installation operations without having to resorttothe use of tools.

These and other objects are attained inthe:

socket holding device described in the ,fol-

H lowing specification andillustrated in theaccompanying drawing, inwhich Fig. 1 is a side elevation, partiallyin-sed tion and illustratedfragmentally, showing a lamp bulb and connector mounted in a reflec-' 2tor equipped with the deviceembodyingmy invention. p t t Fig. 2 is aview upon enlarged scale, taken I on the line 2-2 of Fig. 1, showing theim,-

proved device installed with'relation to the connector mounted therein,with the reflector tube cooperating with the device to show the.

position of the cooperating parts.

In the usual automobile head lamp, reflec-' tors are provided which,like there'flector 3,

' shown fragmentally inFig. 1, contain the connector 4 which is mountedfor reciprocaprojected by the lamp.

In my improved construction, Ihave in a most simple manner; overcomethese difliculties by providing but-one element which will positivelyprevent axial movement of the connector and its mounted lamp bulb, aswell' signature.

7 which clips around the reflector tube 5 for this purpose. At one endofthe spring a pin 8 is riveted, while at theother end an inwardly'bentfinger 9 is provided, both. ends 10 and 11 of the spring being turnedoutwardly to permit it to be sprung over the reflector j tube. Whenspring 7-is in position, as shown in Figs. :1 and 2,.its'pin 8 occupiesholes 12] and 13in the tube 5 and connector 4 respec tively so that theconnector is held against both rotary movement and axial movement.

pies a slot 14 in the reflector tube and bears With the pin in thisposition, finger 9' occui upon the" connector by extending thereeijthrough. In this manner vibration of the connector is prevented. Thuswith but'one simple agencythe connector is in all respects held againstmovement so. that .the light source remains fixedly in the focal centerof g Disconnection is efl'ected very easily pulling upon endfll to slipthe spring froin" mounted position on the reflector tube, thus thereflectorr freeing all the parts.

: Having thus described my invention, what Iclaim is; i

A lamp socket holding d'evice for automobile lamps, comprisingiii-combination with a mounting tube and a connectonmounted therein,a'C-shaped spring mounted .on the tube detachablybypartialcircumferential engagement therewith, and apin on one end ofthe springloosely engaging holes in the I tube and the connector thereby lockingthe connector against rotary and axial movement, in the tube, theoppositeend of the spring being bent toward the tube, said tube havingan opening therein to receive the opposite end of the springto permit ofits bearing engagementiwith the wall of the connectjonthe tips of thetwo, ends of the spring being 7 bent outwardly to facilitate removaland'replacement of the spring on the tube.
